a retractable frame rotatable about the shank smooth portion, the retractable frame having:
a first choke slidingly engaged with the shank smooth portion toward the head collar;
a second choke slidingly engaged with the shank smooth portion toward the threaded collar;
a plurality of upper frame arms having a first length and pivotally attached at a first upper frame arm end to the first choke;
a plurality of lower frame arm having a second length longer than the first length, the lower frame arms pivotally attached at a first lower frame member end to the second choke;
a plurality of pivot pins for pivotally securing each corresponding lower frame arm second end opposite the lower frame arm first end to upper frame arm second end opposite the upper frame arm first end; and
a spring disposed on the shank smooth portion between the first choke and the second choke wherein the spring urges the first choke away from the second choke;
wherein the first member has a first member opening and the leveling fastener is insertable through the first member opening when the retractable frame is in a collapsed position; and
wherein the threaded portion engages the second member for urging the retractable frame through the first member opening and subsequently expanding the retractable frame the collapsed position to an extended position moving the first member toward the second member and firmly securing the first member a distance from the second member.
2. The fastener according to claim 1 wherein the plurality of upper frame arms each comprise a first upper arm pivotally attached to a second upper arm.
3. The fastener according to claim 1 including a shank opening extending from a first shank end to a second shank end opposite the first shank end and a plurality of extrusion opening extending across the shank length and intersecting the shank opening whereby a fluid is injected in the shank opening and distributed to each of the plurality of extrusion openings.
4. The fastener according to claim 1 including a protective cap disposed over the retractable frame.
5. The fastener according to claim 1 including a fixed path channel for control of the retractable frame.
6. A fastener comprising:
an upper shank having:
a first upper shank end and a second upper shank end opposite the first upper shank end;
a head attached to the first upper shank end, the head having a tool slot for engaging a tool, the tool slot directed away from the shank end and a lower head surface adjacent the shaft;
a head collar adjacent the head;
an upper shank attachment groove disposed adjacent the second upper shank end;
a lower collar disposed proximate to the upper attachment groove;
a shank smooth portion disposed between head collar and the threaded collar;
a grip washer disposed along the collar having a first washer side having a plurality of protrusions and a second washer side having a profile corresponding with the lower head surface, wherein the grip washer is rotatable about the collar and the lower head surface;
a retractable frame rotatable about the shank smooth portion, the retractable frame having:
a first choke slidingly engaged with the shank smooth portion toward the head collar;
a second choke slidingly engaged with the shank smooth portion toward the threaded collar;
a plurality of upper frame arms having a first length and pivotally attached at a first upper frame arm end to the first choke;
a plurality of lower frame arm having a second length longer than the first length, the lower frame arms pivotally attached at a first lower frame member end to the second choke;
a plurality of pivot pins for pivotally securing each corresponding lower frame arm second end opposite the lower frame arm first end to upper frame arm second end opposite the upper frame arm first end; and
a spring disposed on the shank smooth portion between the first choke and the second choke wherein the spring urges the first choke away from the second choke;
a lower shank having a lower shank attachment groove disposed adjacent one end of the lower shank and having securing threads along an opposite end of the lower shank;
a rotatable hinge engageable with the upper shank attachment groove and the lower shank attachment groove for pivotably securing the upper shank with the lower shank.
7. The fastener according to claim 6 including a shank opening extending from a first shank end to a second shank end opposite the first shank end and a plurality of extrusion opening extending across the shank length and intersecting the shank opening whereby a fluid is injected in the shank opening and distributed to each of the plurality of extrusion openings.
8. The fastener according to claim 6 including a protective cap disposed over the retractable frame.
9. The fastener according to claim 6 wherein the rotatable hinge is a flexible hose.
10. The fastener according to claim 6 including a fixed path channel for control of the retractable frame.
11. The fastener according to claim 6 wherein the plurality of upper frame arms each comprise a first upper arm pivotally attached to a second upper arm.
12. A delivery fastener for delivery of a fluid, the fastener comprising:
a cylindrical shank having;
a first shank end and a second shank end opposite the first shank end;
a head attached to the first shank end, the head having a tool slot for engaging a tool, the tool slot directed away from the first shank end;
a threaded shank portion having securing threads, the threaded shank portion disposed along a portion of the second shank end;
an elongated axial shank opening extending from the head toward the second shank end and a plurality of extrusion openings extending radially outward from the elongated axial shank opening whereby a fluid is injected in the shank opening and distributed to each of the plurality of extrusion openings.
13. The delivery fastener according to claim 12 including a frame for allocating space for extrusion of the fluid from the extrusion openings.
14. The delivery fastener according to claim 13 wherein the frame is a retractable frame retractable from a first position wherein the frame is in an extended position for delivery of the fluid to a second position wherein the frame is collapsed for insertion of the delivery fastener through a surface opening in a surface to be secured.
15. The delivery fastener according to claim 13 including a grip washer having a first surface having protrusions for gripping a surface and a second surface having a profile corresponding to a lower surface of the fastener head.Join the waitlist — get patent alerts
